I was able to re-provision phones manually, and I was also able to option 160 , only if the phones are set to Custom + option 66 . If the phones are set to static then it seems to ignore the DHCP option.

This seems to work on a small scale . I just have to try it out on 60 + phones all at one time. It looks like as long as the phone is not set to Static instead of Custom + Option 66 that it wake the option 160 from DHCP after a reboot.

I could have done the testing first, but I was just curious if anyone else has done this before. Using DHCP should be easier then trying to modify the cfg files.

I don't think that these phones are locked to the old service. I was able to change several phones to the new provisioning server without any problem. If they were locked then we could ask them to remove the phones from the redirect servers, since they aren't leased. The admin password on all the phones are default, but their configuration file disables the phone's web GUI, which is unfortunate.
